well, she left the obama white house about a year ago. she's with us now on inauguration day here on the national mall. melody, four years ago, it was history. it was hope. it was change. as this president begins the second term, still a sluggish economy, a polarized political environment, what is the number one challenge as he prepares to address the american people tomorrow? >> well, i still think it is about the hope of the american people, and it is still historic, the second inauguration of this president. but at the same time, obviously, it's going to be working with congress to get the economy moving, moving forward in terms of the big initiatives that the president considers to be so important with regard to immigration reform, implementation of health care reform and making sure that everybody has an opportunity, has a shot at the american dream. >> you mentioned health care reform. you know, republicans would say he did that first last time. he got in our face. that ruined the environment. i know each side blames the other side.
